Active radicals formed during the sonolysis of PVK (polyvinyl carbazole) and PMMA (polymethylmethacrylate) have been studied with the combination of spin thepping technique and ESR spectroscopy-The results show that: 1. For PVK
radicals CA and--CH2--CH--are produced during the ultrasonic irradiation and only the later can be trapped by MNP. 2. For PMMA
radicals --C and --CH2 are generated by sonolysis and both can be trapped by ND.
